The message comprises neighbour cell information to assist the user equipment in handling mobility in idle mode | 02-04-2010 |
20100210297 | Method and Arrangement in a Telecommunication System - The present invention provides a user equipment for a telecommunications system, the telecommunications system comprising at least a first radio basestation. The user equipment comprises means for controlling a transmission power of the user equipment, such that said transmission power has a first value for a first set of one or more signals sent over a physical channel between the user equipment and the first radio basestation. The first value and said second value are different. In alternative embodiments, the second set of signals are transmitted taking into account information from the serving cell and a neighbouring cell, while the first set of signals are transmitted taking into account information from the serving cell only. | 08-19-2010 |
20100246519 | METHOD AND ARRANGEMENT IN A TELECOMMUNICATION SYSTEM - A method of controlling an unsynchronized cellular wireless telecommunication system includes, for at least one user equipment served by a first cell, receiving signal strength measurements and, based on the signal strength measurements, determining whether the user equipment should be scheduled for a low interference time period during which neighbouring cells are configured to minimize interference in the first cell. The method additionally includes receiving neighbouring cell time difference measurements from at least one mobile device within the first cell and, based on said measurements, determining a timing of transmissions from at least one neighbouring cell relative to a timing of transmissions from the first cell. Additionally, the method includes defining the low interference time period based on the determined timing of transmissions from the at least one neighbouring cell. | 09-30-2010 |
20100248750 | Paging in a Radio Access Network, Such As An E-UTLRAN - The present invention relates to methods and arrangements of a network node and a UE of a radio access network supporting discontinuous reception, offering a solution that is based on the idea to use more than one sub frame for transmitting paging messages when needed. An indicator in a sub frame with paging messages indicates to the receiving UE if the subsequent sub frame should be read as well. | 09-30-2010 |
20100309797 | Signal Measurements Based on Sync Signals - Methods and apparatus for determining a load estimate in a receiver in an orthogonal frequency division multiplex (OFDM) communication system include detecting at least one OFDM symbol of at least one predetermined synchronization signal; determining a signal strength measure based on the detected at least one synchronization symbol; detecting at least one OFDM symbol nearby to the OFDM symbol of the at least one predetermined synchronization signal; determining a total signal power measure based on the detected at least one nearby OFDM symbol; and determining the load estimate based on the signal strength measure and the total signal power measure. | 12-09-2010 |
20100330999 | Handover Support in Radio Communications - User equipment is to be handed over from a source cell to a target cell in a radio communication network. The user equipment is assigned dedicated uplink resources in the source cell, and a handover candidate cell is prepared for receiving the user equipment by obtaining information about the assigned dedicated uplink resources in the source cell. A radio base station for the handover candidate cell is listening for user equipment transmissions and determines, when receiving a user equipment transmission, whether the received user equipment transmission can be detected based on information about the assigned dedicated uplink resources in the source cell in order to assess if the received user equipment transmission is coming from user equipment for which the handover candidate cell has been prepared. The radio base station for the handover candidate cell initiates a handover procedure for the user equipment if it is assessed that the received user equipment transmission is coming from user equipment for which the handover candidate cell has been prepared. In this way, handover can be initiated and completed even if the serving radio base station of the source cell cannot receive a handover-triggering measurement report from the UE. | 12-30-2010 |
20110002307 | Controlling Node - A controlling node for a cellular communications system, arranged to handle the control of one or more user terminals in a first cell and configurable to receive transmissions from one or more user terminals in the first cell, with a defined periodicity. The controlling node includes a receipt monitor for one or more users in the cell, the receipt monitor being arranged to monitor timely receipt of the one or more of the certain transmissions from the one or more user terminals at the expected time for the defined periodicity, and to initiate handover of a user terminal from the first cell to another cell if the controlling node does not receive one or more of the certain transmissions at the expected time for the defined periodicity from the user terminal. | 01-06-2011 |
20110170418 | Measurement Event Evaluation for Triggering Measurement Reports - Measurement event evaluation is of interest in a user equipment (UE) configured with multiple downlink component carriers (CCs). The UE performs measurements of a neighbor and a specific one of the configured CCs, being used as a reference CC. The UE evaluates, based on the measurements of the neighbor and the reference CC, being a specific one of the configured CCs, an evaluation criterion for triggering a measurement report from the UE. In this way, the number of event evaluations and measurement reports can be reduced, since a specific reference CC is used for the purpose of measurement event evaluation in a scenario when the UE is configured with multiple CCs. | 07-14-2011 |
20110177820 | TELECOMMUNICATIONS SYSTEM AND METHOD - The present invention overcomes the problem of S1 interface failure by redirecting user equipments to another radio basestation, or another RAT. This redirecting may be on a UE-by-UE basis, i.e. when a connection request is received, redirecting that UE, or may involve redirecting all UEs in a cell by broadcasting modified system information. The redirecting may be such that future traffic load, for example as caused by UEs performing tracking area updates, is minimized, by instructing UEs to redirect after a randomized period of time, or by locking the cell after a randomized period of time, for example. In yet further embodiments of the invention, the cell may be locked after a certain number of connection requests have been received. In this way, particularly busy cells can be locked sooner than would otherwise be the case. | 07-21-2011 |

20110212693 | Measurement Handling with Carrier Aggregation - Measurement handling is of interest in a user equipment (UE) in connected mode, with the UE being configured with multiple downlink component carriers (CCs). The UE evaluates the signal quality of a specific CC of the configured CCs against a configurable threshold to determine the need for neighbor cell measurements. The UE performs neighbor cell measurements if the signal quality of the specific CC is below the configurable threshold. In this way, robust and efficient measurement handling is provided, even though the UE is configured with multiple component carriers. | 09-01-2011 |

The present invention provides improved methods and arrangements for reporting cell measurements without significantly increasing the complexity in the cell measurement procedure. The user equipment reports the number of transmit antenna ports used for performing cell measurements on each of the neighbouring cell in its measurement report to the network node. The network node receives the number of transmit antenna ports which enables the network to be aware of the actual number of antenna ports that are used for cell measurements. | 09-08-2011 |

The RAN relay cell identifier is then provided or used as needed so that the relay radio node can transmit the RAN relay cell identifier to uniquely identify the relay cell to one or more radio terminals in the RAN. | 10-06-2011 |
